This is a very basic level of elearning course. We have used PowerPoint® as a format that can be used for eLearning courses.

4. Types of Transformers

5. Autotransformers
An autotransformer has
only a single winding, which
is tapped at some point
along the winding. AC or
pulsed voltage is applied
across a portion of the
winding, and a higher (or
lower) voltage is produced
across another portion of
the same winding.

6. Constant Voltage Transformer
By arranging particular
magnetic properties od a
transformer core, and installing
a resonant tank circuit (a
capacitor and an additional
winding), a transformer can be
arranged to automatically keep
the secondary winding voltage
constant regardless (within
some limits) of any variance in
the primary supply without
additional circuitry or manual
adjustment.

7. Polyphase Transformers
For three-phase power,
three separate single-phase
transformers can be used,
or all three phases can be
connected to a single
polyphase transformer. The
three primary windings are
connected together and the
three secondary windings
are connected together.

8. Resonant Transformers
A resonant transformer
operates at a resonant
frequency of one or more
of its coils and (usually) an
external capacitor. The
resonant coil, usually the
secondary, acts as an
inductor, and is connected
in series with a capacitor.

9. Instrument Transformers
These comes in various types, such as:
1.Current Transformers
2.Voltage Transformers
3.Pulse Transformers
4.RF Transformers
5.Baluns
6.Audio Transformers
7.Speaker Transformers
8.Small Signal Transformers
9.‘Interstage’ and coupling Transformers

22. Carbon Capture & Storage
• Carbon capture and storage (CCSD) is an approach to mitigating climate change by
capturing carbon dioxide from large point sources such as power plants and
subsequently storing it away safely instead of releasing it into the atmosphere.
Technology for capturing of carbon dioxide is already commercially available for
large carbon dioxide emitters, such as power plants.
• Storage of carbon dioxide, on the other hand, is a relatively untried concept and as
yet (2007) no power plant operates with a full carbon capture and storage system.
Currently, the United States government has approved the construction of the
world's first CCS power plant, FutureGen, while BP has indicated that it intends to
develop a 350 MW carbon capture and storage plant in Scotland, in which the
carbon from a natural gas fired generator plant will be stripped out and pumped
into the Miller field in the North Sea.
• Storage of the carbon dioxide is envisaged either in deep geological formations,
deep oceans, or in the form of mineral carbonates. In the case of deep ocean
storage, there is a risk of greatly increasing the problem of ocean acidification, a
problem that also stems from the excess of carbon dioxide.
